CONVECTION IN THE NEIGHBORHOOD OF LINEAR ELONGATED SOURCES. NUMERICAL SOLUTIONS OF THE NAVIER-STOKES EQUATIONS

Convective air motions in the neighborhood of linear elongated heat sources of various configurations are investigated by numerically solving the Navier-Stokes equations. The situations considered can be observed in specialized rooms of optical systems when air is heated by beams of optical radiation of varying intensity. The convection that occurs due to the heating of the air by radiation, as well as the emerging fields of turbulence, have a significant impact on the operation of recording devices. Consideration of the emerging convective and turbulent phenomena is necessary to predict the correct operation of such devices.
